Hello Nilesh,

Sure, Here is my sample code. 

function WebGrid1_OnAfterResponseProcess(controlId, actionName, lastRequestObject, xmlResponseObject)
{
	var WebGrid1 = ISGetObject(controlId);
        var button=document.getElementById("Button1");
        if (actionName == "Charting") 
        {
                button.style.display = "none";
        }
		return true;
}

Unfortunately, server side does not have any method such as setText() in client side.
All cell modification only could be done in clientside events.

Hello Piere,

In my test sample, After I edited a cell, click on scrollbar and then click on the outside of WebGrid, the lost focus is not called.
But if I edit a cell and click outside of WebGrid, lost focus is called. Is this issue that you were trying to say? If yes, I will forward this issue to our developer teams.

Hello,

After you delete a row, you will need to call grid.AcceptAllChanges(). With this way, all changes would be saved into your database.
